Kalyani is a melakarta raga (parent musical scale) in the Carnatic music. It was called Kalyan but is now more popularly called Yaman in Hindustani Music. Its Western equivalent is the Lydian mode.

In South Indian weddings it is a very prominently played raga. The word Kalyani means she who causes auspicious things. It is the 65th melakarta raga under the Katapayadi sankhya. It is also called Mechakalyani. The notes for Kalyani are S R₂ G₃ M₂ P D₂ N₃. Kalyani is the first Prathi Madhyama raga that was ever discovered. It was obtained by the process of Graha Bhedam or modal shift of tonic of the ancient Shadja Grama.^[1]

Nearly every significant Carnatic composer (including the Trinity of Carnatic music) has composed several pieces in the Kalyani ragam. Kalyani is considered one of the "major" ragams of Carnatic music along with Sankarabharanam, Todi and Kharaharapriya (the set of "major" rāgams is an informal grouping of the most popular Melakarta ragams used for elaboration and exploration, and which often form the centerpiece of a Carnatic music concert in the form of a Ragam Tanam Pallavi (RTP) or a kriti). See Related ragams section for further information on relationships between these ragams. The state anthem of Mysore, Kayou Shri Gowri is also set in this raga. Here is a short list of compositions in Kalyani.

Yaman/Aiman is not an ancient raga. It is first mentioned in the literature in the late 16th century, by which time it was very popular: The Sahasras contains 45 dhrupad song-texts for Kalyan and five for Iman-Kalyan. According to Venkatamakhin (1620), Kalyan was a favourite melody to the Arabs, and Pundarika included Yaman among his 'Persian' Ragas.^[4]
